Abstract: Adjustable-size wrench having an elongated case defining a chain-storing elongated channel, and with an anvil fixed at one end of the case, the wrench comprising a linked driver chain adjustable around the anvil and a tooth on the anvil so as to be adapted for driving any of a number of different drivable item, e.g., nut, sizes on the anvil, the linked driver chain being adapted for being stored with a portion thereof releasably retained within the elongated case by a plurality of nubs on pedestals at least partially housed within the case. A multitool portion may further comprise a plurality of tools of at least one of a flat-head screw driver, a phillips-head screw driver, and a knife blade, each of the plurality of tools pivotably housed at least partially within a partially-enclosed elongated channel opposing and divided from the chain storing channel by a central base member.

Abstract: Portable holder adapted for attachment to a larger device and for holding articles, comprising: an elongated tubular at least partially hollow case defining at least one interior cavity, the case having first and second ends and defining at least one opening into the interior cavity of the case; at least one repeatedly-openable moisture-resistant cover on and corresponding with the at least one opening for sealingly closing the opening to the interior cavity; either a permanently-fixed mounting bracket attached to the case, or alternatively a separate quick-release bracket, each adapted for interfacing the case with the larger device; a plurality of grooves defined in the case adapted for optionally receiving a corresponding plurality of elongated cinchable strap members for securing the case to the larger device.

Abstract: Methods, systems, and compositions for clarifying drilling mud are provided. A method of clarifying drilling mud includes at least: mixing a hydrophilic solution and an effluent; the effluent comprising an oil lubricant and solid particles; binding the solid particles to the hydrophilic solution; separating the oil lubricant from the solid particles; and recovering the oil lubricant. A system includes at least: a mixing tank for mixing a hydrophilic solution and an effluent, the effluent comprising an oil lubricant and solid particles, and creating a mixture; and a centrifuge connected to the mixing tank, the centrifuge being capable of receiving the mixture and separating the hydrophilic solution, the solid particles, and the oil lubricant, and discharging the separated oil lubricant. A composition for clarifying drilling mud includes at least: a homogeneous mix of at least one hydrophilic substance.
